Earthrise - Super Box Set (Book 1-6)

I gave the series a try, but I'm giving up a couple of chapters into book four. The plot holes are massive, and each book follows the same pattern: gore, miraculous survival of the protagonists, everyone else dies. Lather, rinse, repeat. Maybe I'm seeing them through a lens of having just finished a long time with Terry Pratchett novels, but the story here couldn't hold me any longer.
